Introduction-
The U807 is Ni Hui’s entry into the very crowded Letrax Alias styled quadcopter market. With a market as big as this one it is easy to get lost, the U807 doesn’t have to worry about that. With deep pitch, fast yaw, and awesome stability this quadcopter is easily one of the best Alias styled quads on the market.
Specifications (as tested)-
Frequency- 2.4ghz
Battery- Quadcopter 650mah (included)
Transmitter 4x AA batteries (not included)
Flight time- 7:30 WITH prop guards
7:45-8 min WITHOUT prop guards
*Adding the camera will take roughly 1 minute off of flight time
LVC- 20 seconds
Charging time- 1hr with stock USB charger
Control distance- Over 150m
Camera- 2MP with video and still shot function
Unboxing
Transmitter-
At first glance the transmitter looks a little big and clunky, but once you get it in your hands you find that it is very comfortable to use. It’s got a nice back lit LCD that shows your trims and lets you know if you are recording or not, but interestingly it doesn’t show what rate you are in. The left shoulder button moves you through the rates, there is three rates ranging from docile to very sporty, you only have one yaw rate but I have found that it is pretty fast and very controllable so that’s not a problem at all. The right shoulder button has different functions based on how the quadcopter is setup, if you have the camera mounted a short press takes a still shot and holding it for 2 seconds starts recording, holding it for two seconds again will stop recording. If the camera is not mounted the right shoulder button is you flip button, push it once then input what direction you would like to flip and the quadcopter will flip once and come out of flip mode. Last is the right stick, if you push this in the quadcopter will enter headless mode, now I have found that even after calibration the headless mode is ok at best, if you try to use it in high rates the quadcopter gets all wobbly and out of control so I just don’t use it. To calibrate the accelerometers you will hold the sticks down left, once the lights stop flashing the accelerometers have been reset, to calibrate the headless mode compass you hold the sticks down and in towards each other, once the lights begin to flash you rotate the quadcopter on a flat surface until they go out. Last holding both sticks down right will switch the quadcopter between prop guard mode and no prop guard mode. The lights will flash fast indicating that the copter is in prop guard mode, this basically helps the quadcopter from over shooting a flip with the added weight of the prop guards. If you do it again the lights will flash slow indicating that you are not in prop guard mode, in this mode it flips much quicker. If you find the flips aren’t working as well as they should, land it and make sure you are in the correct mode.
Quadcopter-
The quadcopter has a really cool design, the canopy kind of looks like a race car with these sleek likes.
The prop guards work well and have these little turn ups here that protect it from the ceiling as well.
Moving in a little you can see that the gears are exposed but are mounted on the top which really protects them from getting nicked or getting debris in them.
There are nice bright LED’s mounted in the arms and since the whole arm is the lens it really lights up nice at night, there is also a green LED here on the back that flashes when you are flying, this also helps with night time orientation.
There is a 650mah battery that takes just about one hour to charge and gives you just under 8 minute flights with no prop guard and no camera, the prop guards take about 30 seconds off the flight bringing you to about 7 min 30 sec and the camera takes about a full minute off of the flight time. So definitely some nice long flight times.
The camera that is included in the camera version is a 2mp camera with a nice adjustable lens, it looks like it would give decent video but unfortunately there is just way too much vibration on this model to give decent video, you may have better luck if you balance the props but I just haven’t done that yet, but out of the box the video has loads of vibration and jello in it.
Flight Test-
The first thing I noticed while flying this quadcopter is how quiet it is, this model is super quiet. In flight it is clear that this model is geared more towards sports flight than aerial video, the yaw is very fast and the pitch is fairly aggressive allowing for deep funnels. Even with its aggressive flight capability the quadcopter is also extremely stable, you can easily hover in place with your hands off the transmitter. The quadcopter flips and recovers very well with or without the prop guards and carries its momentum well allowing for barrel rolls and flips while in motion. Several attempts at getting the headless mode to work properly (even after calibrating the compass) proved it to be OK at best, it would start out with the proper heading but eventually lose its way. Interestingly enough the headless mode acts much like the WL Toys V686 series, I’m not sure this is a coincidence because they are both on the same protocol (the right stick inputs are reversed), the lighting is similar with the blinking green light on the rear, and before its first takeoff after binding all of the lights flash very quickly. It almost seems as if they have the same flight controller in them, although the boards are different.
Conclusion-
After many flights the only word that I can find to properly describe the U807 is awesome! Leaving the price tag out of the equation the U807 is a must have, then once you consider the low price it’s a no brainer. If you’re strictly in the market for an aerial video platform this may not be the model for you. But if you’re in the market for a fun, sporty, inexpensive outdoor flyer look no further than the U807, I guarantee you won’t be disappointed.
Pros-
Long flight times
Fast/sporty flight
Long range
Plug in motors
Bright LEDs (great night flyer)
Large comfortable transmitter
Cons-
Lots of vibration in video/still shots
Inaccurate headless mode
